Answer:
Part A:
The vertex : x = - b / 2 a = - 28 : ( - 2 ) = 14
y = f ( 14 ) = - 14² + 28 · 14 - 192 = 196 + 392 - 192 = 4
The vertex is ( 14, 4 ). It means that the maximum hourly profit is $4, and that the shop should sell 14 sodas to reach the maximum.
Part B :
We will solve the quadratic equation:
x 1/2 = ( - 28 +/- sqrt ( 784 - 768 ) ) / ( - 2 )
x 1 = 12, x 2 = 16.
It means that if the shop must sell more than 12 and less then 16 sodas if they want to make a profit ( 13, 14, or 15 ). If they sell 12, or 16 they will brake even.
I think
Answer: 12
According to the box plot, the medians are marked in the middle (those middle lines). Find the difference by subtracting 84 - 73 = 12

Answer:
1. C
2. C
Step-by-step explanation:
1. x =
, y = 4t +3
Solve for t:
t =
Plug in t:
y = 4(
) +3
y = 4
+3
2. x = 2t, y = t + 2
Solve for t:
t = x/2
Plug in t:
y = 1/2x + 2
Answer:
Alright well solve for b by simplifying both sides of the equation, then isolating the variable
Exact form: b = 29/11
Decimal form: b = 2.63 Well Hope this helps :)
